Topological dynamics characterization for layered satellite networks

The highly topological dynamics characterize the most fundamental property of satellite networks contrary to the terrestrial networks. This manifest feature directs the researches on various aspects of satellite networks, including routing and switching architecture selection, routing protocol and reliable transmission control protocol design and enhancement, etc,. The paper quantifies the dynamical activates of layered satellite network topologies. The number and length of network snapshots of one-layered satellite constellations are formulated concisely. The snapshot distributions of typical multi-layered constellations are also evaluated. With this work, it compensates for the simplified topological assumptions in many satellite network related investigations. The thorough understanding of this basic feature not only provides for an accurate quantification of network behavior, but also guides constellation design for future satellite networks
